Description

[0001] This application claims priority to United States Patent Application No. 60/859,946, filed on November 20, 2006. The disclosure of the above application is incorporated herein by reference.

[0002] The present disclosure relates to vacuums and more particularly to a wet/dry vacuum having multiple operating modes.

[0003] Wet/dry vacuums may be used to collect solid materials such as dirt, debris etc., as well as liquids, such as water etc. In some examples, a hose may be connected on a first end to an inlet port on a collection tub. A motor may be disposed within or about the vacuum that is operable to drive an impellor. Rotation of the impellor may create a vacuum pressure to siphon or otherwise urge the solid and/or liquid material through the hose and into the collection tub. In some examples, the hose may be connected at an opposite end to a hand held tube or accessory. During use, an operator may manually move the hand held tube or accessory onto or near the solid and/or liquid to be vacuumed.

[0004] A vacuum can include a housing having an inlet adapted to receive debris being vacuumed. A mounting bar can be fixedly coupled to the housing. A floor collector assembly can be rotatably disposed about a first axis defined by the mounting bar. The floor collector assembly can include a first debris-passing member coupled to the mounting bar, a second debris-passing member rotatably coupled to the first debris-passing member and a third debris-passing member removably coupled to the second debris-passing member. The first debris-passing member can define an opening. The floor collector assembly can be operable in a plurality of modes. The modes can include a first mode, a second mode and a third mode. In the first mode, the opening can be substantially perpendicular relative to a vacuumed surface. In the second mode, the second debris-passing member can be rotated relative to the first debris-passing member about a second axis such that the opening is at an acute angle relative to the vacuumed surface. In the third mode, the third debris-passing member is coupled to the second debris-passing member wherein a passage defined through the third debris-passing member is substantially parallel to the vacuumed surface.

[0005] According to other features, the first axis can intersect the second axis. One of the first or second debris-passing members can define a collar. The other of the first or second debris-passing members can define a bore. The collar can rotate within the bore about the second axis during rotation of the second debris-passing member relative to the first debris-passing member.

[0006] According to still other features, one of the first or second debris-passing members can define a hub. The other of the first or second debris-passing member has a pair of fingers that define a notch. The hub can positively nest in the notch in a first position at any of the operating modes. The hub can ramp out of the notch over one of the fingers upon sufficient force during movement of the second debris-passing member out of the first position. The first debris-passing member can define opposing clam-shell portions that cooperate to form a first and a second pair of opposing planar sides. The second debris-passing member can define a back surface and a first pair of opposing surfaces. One surface of the first pair of opposing surfaces can be larger than the corresponding opposing surface of the first pair such that the opening defines an acute angle relative to the back surface. The back surface can oppose the first debris-passing member.

[0007] Further areas of applicability will become apparent from the description provided herein. It should be understood that the description and specific examples are intended for purposes of illustration only and are not intended to limit the scope of the present disclosure.

[0009] With initial reference to FIG. 1, an exemplary vacuum constructed in accordance with the present teachings is shown and generally identified at reference numeral 10. The vacuum 10 can generally include a housing 12, a cover 14, a motor assembly 16, and a floor collector assembly 20. The floor collector assembly 20 can be rotatably coupled to a mounting bar 22 extending from the housing 12. The motor assembly 16 can be disposed within the housing 12 and/or the cover 14. The motor assembly 16 can include a motor 26 that drives an impeller (fan) 28 through an output shaft 30. The motor 26 can be powered by an AC source by way of an electrical plug 32. An on/off switch (not shown) may be provided on the housing 12 or cover 14. An inlet 34 can be defined on the housing 12. An intake port 36 can be integrally formed or otherwise coupled to the housing 12 at the inlet 34. During operation of the vacuum 10, rotation of the impeller 28 can cause suction within the housing 10 for ingesting debris and/or liquid through the inlet 34. Exhausted air may exit the housing 12 at an outlet port (not specifically shown).

[0010] The exemplary vacuum 10 can define a cube-like shape having opposing front and rear sides 40 and 42 connected between opposing connecting sides 44 and 46. A first and second pair of wheels, 48 and 50, respectively, may be coupled to the vacuum 10 for rolling the vacuum 10 across a floor. The first pair of wheels 48 (only one shown) may be fixed for rotation about an axle 54 that defines an axis generally parallel to the front and rear sides 40 and 42. The second pair of wheels 50 can be caster wheels that rotate about axles within respective carriers 58. The carriers 58 can be coupled to the mounting bar 22 for rotation about respective axes 60. Other wheel configurations may be employed.

[0011] A pair of latches 62 (only one shown) can be disposed on the opposing sides 44 and 46 of the vacuum 10. Description of the exposed latch 62 on the opposing side 44 will now be described while it is appreciated that the same latch configuration may be provided on the other opposing side 46. The latch 62 can generally define a mounting bore 64 on a first end and a curved retaining portion 66 on a second end. The latch 62 can be mounted about a shaft 68 extending in a pocket 70 defined on the opposing side 44. The latch 62 can rotate about the shaft 68 between a secured position (solid line, FIG. 1) wherein the curved retaining portion 66 captures a ledge 74 of the cover 14, and an unsecured position (phantom line, FIG. 1). In the unsecured position, the cover 14 can be lifted (i.e. in a direction upward as viewed in FIG. 1) away from the housing 12 for accessing the motor assembly 16 and/or emptying the vacuumed contents from the housing 12. The cover 14 can define a pair of handles 76 formed thereon. An operator can grasp the handles 76 to move the vacuum 10 as a whole or lift the cover 14 away from the housing 12.

[0012] With continued reference to FIG. 1 and additional reference to FIGS. 2 and 3, the mounting bar 22 and floor collection assembly 20 will be described in greater detail. The mounting bar 22 can define a tubular member having a linear central portion 80, a pair of linear end portions 82, and a pair of curved portions 84 that transition between the linear central portion 80 and the linear end portions 82. Apertures 86 can be formed through the mounting bar 22 for receiving fasteners (not shown) to couple to mounting bar 22 to the housing 12.

[0013] The floor collection assembly 20 can include a connecting duct 90 (FIG. 1), a floor scoop 92, a squeegee adapter 94, and a hose cuff 96 (FIG. 2). The connecting duct 90 can be collectively defined by a first and a second clamshell portion 100 and 102 (FIG. 2), respectively. The first clamshell portion 100 can define a mounting sleeve 104 and a first semi-hemispherical wall portion 106. The mounting sleeve 104 can be adapted to receive the hose cuff 96. First fingers 110 can be formed on a forward face 112 of the first clamshell portion 100. A first annular lip 116 can be formed on the mounting sleeve 104 for cooperatively mating with a second annular lip 118 formed on the hose cuff 96. A first half-cylinder 120 can be defined on the first clamshell portion 100. A second semi-hemispherical wall portion 122 can be defined on the second clamshell portion 102. Second fingers 124 can be formed on a forward face 126 of the second clamshell portion 102.

[0014] The connecting duct 90 can generally define a first and a second pair of opposing sides 130 and 132, respectively in an assembled position (FIG. 3). A mounting bore 136 can be collectively defined by the first and second semi-hemispherical wall portions 106 and 122. The first and second half-cylinders 120 and 122 can cooperatively define a mounting cylinder 140 (FIG. 3) for accepting the central portion 80 of the mounting bar 22 in the assembled position. The connecting duct 90 can be formed of durable lightweight material such as plastic.

[0015] Returning now to FIG. 2, the floor scoop 92 can generally define a first pair of opposing surfaces 142 and 144, a second pair of opposing surfaces 146 and 148, a back surface 150, and a collar 152. An opening 154 is defined collectively by the opposing surfaces 142, 144, 146, and 148. The back surface 150 and the collar 152 can cooperate to define a chute 156. The first surface 142 of the first pair of opposing surfaces 142 and 144 can be larger than the second surface 144 of the first pair of opposing surfaces 142 and 144 such that the opening 154 can define an acute angle β (FIG. 4) relative to the back surface 150. The first surface 142 can define a first sweep edge 158. The second surface 144 can define a second sweep edge 160. The collar 152 can be generally cylindrical and extend from the back surface 150. An annular ring 162 can be integrally formed around the collar 152. A pair of tabs 164 can be formed on the second pair of opposing surfaces 146 and 148, respectively. The back surface 150 can define a pair of hubs 166 (best shown in FIG. 6). The floor scoop 92 can be formed of durable lightweight material such as plastic.

[0016] With continued reference to FIG. 2, the squeegee adapter 94 can define a bottom surface 170, a forward surface 172 and a pair of side surfaces 174 and 176. A longitudinal opening 180 can be formed through the bottom surface 170. A plurality of connecting pins 182 can be formed on the squeegee adapter 94 adjacent to the longitudinal opening 180. In one example, the connecting pins can define Christmas tree retainers although other configurations or arrangements are contemplated. A blade 184 can define a complementary plurality of passages 186 for accepting the connecting pins 182 in an installed position (see also FIG. 16). The blade 184 can define a linear body that substantially corresponds for accommodation by the longitudinal opening 180. A pair of ears 184 can be formed on the pair of side surfaces 176 and 178, respectively. A flap 188 can be formed along the bottom surface 170 of the squeegee adapter 94. The squeegee adapter 94 can be formed of a durable lightweight material such as plastic while the blade 184 can be formed of resilient material such as rubber.

[0017] With reference now to all FIGS., the vacuum 10 according to the present teachings is operable in a plurality of operating modes. More specifically, the floor collector assembly 20 can be manipulated into multiple shapes and orientations to accommodate a given task. The various modes can include a first or "sweep mode" (FIGS. 3-5), a second or "floor nozzle mode" (FIGS. 9-11), and a third or "squeegee mode" (FIGS. 13-16). The vacuum 10 can also operate in a fourth mode wherein a connecting hose 192 coupled between the intake port 36 and the hose cuff 96 of the floor collector assembly 20 is disconnected from the hose cuff 96 and used as a conventional vacuum hose. In the fourth mode, the floor collection assembly 20 can be rotated about the mounting bar 22 to a transportation position (FIG. 1).

[0018] With particular reference now to FIGS. 3-5, operation of the vacuum 10 in the "sweep mode" will be described in greater detail. In the "sweep mode", the connecting duct 90 is rotated about an axis 200 defined by the mounting bar 22 such that the first sweep edge 158 slides against or substantially adjacent to a vacuumed surface 202. The connecting hose 192 can be coupled between the intake port 36 and the hose cuff 96. In this position, the opening 154 of the floor scoop 92 can define an angle α1 relative to the vacuumed surface 202. The angle α1 can be substantially about 90 degrees. It is appreciated that this angle can be altered by rotating the connecting duct 90 about the mounting bar axis 200. The annular ring 162 (FIG. 5) of the floor scoop 92 can nest within an annular pocket 206 defined inboard of the first and second semi-hemispherical wall portions 106 on the connecting duct 90. In the "sweep mode," the floor scoop 92, the connecting duct 90 and the connecting hose 192 each act as sequential debris-passing ducts to direct the vacuumed material into the housing 12.

[0019] With continued reference to FIG. 5 and additional reference to FIGS. 6-8, movement of the floor scoop 92 relative to the connecting duct 90 will be described. In general, the collar 152 (FIGS. 2 and 5) can selectively rotate about an axis 210 (FIG. 5) defined by the mounting bore 136 of the connecting duct 90. During rotation, the annular ring 162 of the floor scoop 92 can ride within the annular pocket 206 of the connecting duct 90 (FIG. 5). As shown in FIG. 7, while in one of the modes (i.e., sweep mode, floor nozzle mode etc.), the hubs 166 (only one shown) of the floor scoop 92 positively nest in a locked position within a notch 212 defined between the fingers 110 and 124 of the connecting duct 90. Upon enough rotational force F (FIG. 8) administered by a user onto the floor scoop 92, the hub 166 can ramp out of the notch 212 over one of the fingers 110 or 124 into an unlocked position (e.g., for free rotation of the floor scoop 92 about the axis 210).

[0020] With particular reference now to FIGS. 9-11, operation of the vacuum in the "floor nozzle mode" will be described in greater detail. In the "floor nozzle mode", the connecting duct 90 is rotated about the mounting bar 22 (e.g., about the axis 200, FIG. 10) such that the second sweep edge 160 slides against or substantially adjacent a vacuumed surface 202. As can be appreciated from the preceding discussion, the floor scoop 92 can rotate 180 degrees about the axis 210 (FIG. 6) from the "sweep mode" position to the "floor nozzle mode", and vice-versa. The connecting hose 192 can be coupled between the intake port 36 (FIG. 1) and the hose cuff 96. In this position, the opening 154 of the floor scoop 92 can define an angle α2 (FIG. 10) relative to the vacuumed surface 202. The angle α2 can be an acute angle. In one example, the angle α2 can be approximately between 25 and 65 degrees. It is appreciated that this angle can be altered by rotating the connecting duct 90 about the mounting bar axis 200. In the "floor nozzle mode," the floor scoop 92, the connecting duct 90 and the connecting hose 192 each act as sequential debris-passing ducts to direct the vacuumed material into the housing 12.

[0021] With particular reference now to FIGS. 12-16, operation of the vacuum 10 in the "squeegee mode" will be described in greater detail. In the squeegee mode, the squeegee adapter 94 is coupled to the floor scoop 92. More specifically, the flap 188 of the squeegee adapter 94 can be located against the first wall 144 of the floor scoop 92. As best illustrated in FIG. 16, a locating ridge 214 defined on the flap 188 can nest within a groove 216 defined on the wall 144 of the floor scoop 92. The ears 184 of the squeegee attachment 94 can ramp over the respective tabs 164 of the floor scoop 92 until they reach a position beyond the ramps 164 (FIG. 13). In the squeegee mode, the bottom surface 170 can be substantially parallel to the vacuumed surface 202 (FIG. 14). Again, It is appreciated that this angle can be altered by rotating the connecting duct 90 about the mounting bar axis 200. The blade 184 can extend through the longitudinal passage 180 for slidably traversing along the vacuumed surface 202. As can be appreciated, the blade 184 can assist in directing liquid (and/or solid debris) to a position near the longitudinal passage 180 to be siphoned. In the "squeegee mode", the squeegee adapter 94, the floor scoop 92, the connecting duct 90 and the connecting hose 192 each act as sequential debris-passing ducts to direct the vacuumed material into the housing 12.
